+.Sh NAME
+.Nm dwarf
+.Nd access debugging information in object files
+.Sh LIBRARY
+.Lb libdwarf
+.Sh SYNOPSIS
+.In libdwarf.h
+.Sh DESCRIPTION
+.Pp
+The
+.Lb libdwarf
+provides functions that allow an application to read and write debugging
+information in object files.
+The format of debugging information accessible through this API
+is defined by the DWARF standard, see
+.Xr dwarf 4 .
+.Pp
+The
+.Xr DWARF 3
+API has two parts:
+.Bl -bullet
+.It
+A consumer API set allows applications to read existing debug information
+in a program object.
+The functions that comprise the DWARF consumer API are described in
+the section
+.Sx "DWARF Consumer API"
+below.
+.It
+A producer API set that allows applications to add debug information
+to a program object.
+The functions that comprise the DWARF producer API are described in
+the section
+.Sx "DWARF Producer API"
+below.
+.El
+.Pp
+Each function referenced below is further described in its own manual page.
+.Ss Namespace use
+The DWARF library uses the following prefixes:
+.Pp
+.Bl -tag -width ".Li Dwarf_*" -compact
+.It Li DWARF_*
+Used for error numbers and constants.
+.It Li DW_*
+Used for constants.
+.It Li Dwarf_*
+Used for types.
+.It Li dwarf_*
+Used for functions and macros that make up the API.
+.El
+.Ss Data Types
+The DWARF(3) API uses the following data types:
+.Pp
+.Bl -tag -width ".Vt Dwarf_Unsigned" -compact
+.It Vt Dwarf_Abbrev
+Describes DWARF abbreviations.
+.It Vt Dwarf_Addr
+A program address in the target object.
+.It Vt Dwarf_Arange
+Describes address ranges.
+.It Vt Dwarf_Attribute , Vt Dwarf_P_Attribute
+Describes attributes of debugging information entries.
+.It Vt Dwarf_Bool
+Used for boolean states.
+.It Vt Dwarf_Cie , Vt Dwarf_P_Cie
+Describes call information that is common to several frames.
+.It Vt Dwarf_Debug , Vt Dwarf_P_Debug
+An opaque type describing a debug context.
+.It Vt Dwarf_Die , Vt Dwarf_P_Die
+A debugging information entry.
+.It Vt Dwarf_Fde , Vt Dwarf_P_Fde
+A frame descriptor.
+.It Vt Dwarf_Func
+A descriptor representing a function.
+.It Vt Dwarf_Global
+A descriptor representing a global name.
+.It Vt Dwarf_Half
+A 16-bit wide unsigned numeric type.
+.It Vt Dwarf_Handler
+A pointer to an error handling function.
+.It Vt Dwarf_Line
+A descriptor for a source line.
+.It Vt Dwarf_Off
+An unsigned file offset.
+.It Vt Dwarf_P_Expr
+A descriptor for a location expression.
+.It Vt Dwarf_Ptr
+A virtual address used by an application.
+.It Vt Dwarf_Signed
+A 64-bit wide signed numeric type.
+.It Vt Dwarf_Small
+An 8-bit wide unsigned numeric type.
+.It Vt Dwarf_Type
+A descriptor representing a user-specified type.
+.It Vt Dwarf_Unsigned
+A 64-bit wide unsigned numeric type.
+.It Vt Dwarf_Var
+A descriptor representing a static variable.
+.It Vt Dwarf_Weak
+A descriptor representing a weak name.
+.El
+.Ss Error Handling
+.Pp
+Library functions that encounter an error will return with a value
+other than
+.Dv DW_DLV_OK .
+.Pp
+The
+.Lb libdwarf
+allows applications to specify three levels of error handling:
+.Bl -enum -compact
+.It
+Most library functions take a parameter of type
+.Vt Dwarf_Error
+that specifies a location to store an error descriptor in
+case of an error.
+If an error occurs during the execution on an API, and if this
+parameter is non-NULL, then an error descriptor is written to the
+location specified.
+.It
+Otherwise, if the error parameter was NULL, but if an error handler
+was defined for the debug context in use using
+.Xr dwarf_init 3
+or
+.Xr dwarf_seterrhand 3 ,
+then the library will invoke the specified error handler with an error
+descriptor as argument.
+.It
+Otherwise, if a library wide error handler was specified using
+.Xr dwarf_seterrhand 3 ,
+it is called.
+.El
+.Pp
+Error descriptors may be used with
+.Xr dwarf_errmsg 3
+or
+.Xr dwarf_errno 3 .
+.Sh The DWARF Consumer API
+The DWARF consumer API permits applications to read DWARF information in
+an object file.

+Function
+.Fn dwarf_add_arange_b
+adds an address range entry to a producer instance.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF producer instance allocated using
+.Xr dwarf_producer_init 3
+or
+.Xr dwarf_producer_init_b 3 .
+.Pp
+Argument
+.Ar start
+specifies the relocatable start address of the address range.
+.Pp
+Argument
+.Ar length
+specifies the length of the address range.
+.Pp
+Argument
+.Ar symbol_index
+specifies the ELF symbol index of the first symbol to be used for
+relocation.
+.Pp
+Argument
+.Ar end_symbol_index
+specifies the ELF symbol index of the second symbol to be used for
+relocation.
+.Bl -bullet
+.It
+If argument
+.Ar end_symbol_index
+is not 0, the
+.Dv DW_DLC_SYMBOLIC_RELOCATIONS
+flag should have been set on the DWARF producer instance.
+The address value specified by argument
+.Ar start
+will be treated as an offset value from the first symbol,
+and the argument
+.Ar offset_from_end_symbol
+should hold an offset value from the second symbol.
+Application code can retrieve the relocation entries for the
+symbol pair by calling function
+.Xr dwarf_get_relocation_info 3 .
+The relocation entry for the first symbol will have type
+.Dv dwarf_drt_first_of_length_pair
+and the relocation entry for the second symbol will have type
+.Dv dwarf_drt_second_of_length_pair .
+.It
+If argument
+.Ar end_symbol_index
+is 0, argument
+.Ar offset_from_end_symbol
+will be ignored and only one symbol is used for relocation.
+.El
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case
+of an error.
+.Pp
+Function
+.Fn dwarf_add_arange
+is deprecated.
+It is similar to function
+.Fn dwarf_add_arange_b
+except that it cannot handle all possible symbol index values
+and supports only one relocation symbol.
+.Sh RETURN VALUES
+On success, these functions return a non-zero value.
+In case of an error, these functions return 0 and set

+.Sh DESCRIPTION
+Function
+.Fn dwarf_add_frame_fde_b
+adds the call frame descriptor referenced by argument
+.Ar fde
+to a producer instance.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF producer instance allocated using
+.Xr dwarf_producer_init 3
+or
+.Xr dwarf_producer_init_b 3 .
+.Pp
+Argument
+.Ar fde
+should reference a frame descriptor allocated using
+.Xr dwarf_new_fde 3 .
+.Pp
+Argument
+.Ar die
+is ignored by this implementation of the
+.Lb libdwarf .
+.Pp
+Argument
+.Ar cie
+specifies the index of call frame common information entry for
+the frame descriptor.
+Valid indices are those returned by the function
+.Xr dwarf_add_frame_cie 3 .
+.Pp
+Argument
+.Ar symbol_index
+specifies the ELF symbol index of the first symbol to be used for
+relocation.
+.Pp
+The meaning of the arguments
+.Ar virt_addr ,
+.Ar code_len
+and
+.Ar offset_from_end_sym
+depend on the value of argument
+.Ar end_symbol_index :
+.Bl -bullet
+.It
+If the argument
+.Ar end_symbol_index
+is zero, the argument
+.Ar virt_addr
+specifies the relocatable address of the start of the function
+associated with the frame descriptor, the argument
+.Ar code_len
+specifies the size in bytes of the machine instructions for this
+function, the argument
+.Ar symbol_index
+specifies the ELF symbol to be used for relocating the address in
+argument
+.Ar virt_addr ,
+and the argument
+.Ar offset_from_end_symbol
+is ignored.
+.It
+If the argument
+.Ar end_symbol_index
+is non-zero, it specifies the ELF symbol index of the second symbol to
+be used for relocation.
+In this case, the argument
+.Ar virt_addr
+specifies an offset from the relocatable symbol specified by argument
+.Ar symbol_index ,
+the argument
+.Ar offset_from_end_symbol
+should specify an offset from the symbol named by the argument
+.Ar end_symbol_index ,
+and the argument
+.Ar code_len
+will be ignored.
+The
+.Dv DW_DLC_SYMBOLIC_RELOCATIONS
+flag should also have been set on the DWARF producer instance.
+.Pp
+Application code can retrieve the relocation entries for the symbol
+pair by calling function
+.Xr dwarf_get_relocation_info 3 .
+The relocation entry for the first symbol will have type
+.Dv dwarf_drt_first_of_length_pair
+and the relocation entry for the second symbol will have type
+.Dv dwarf_drt_second_of_length_pair .
+.El
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case
+of an error.
+.Pp
+Function
+.Fn dwarf_add_frame_fde
+is similar to function
+.Fn dwarf_add_frame_fde_b
+except that it supports only one relocation symbol.
+.Sh RETURN VALUES
+On success, these functions return the index value for
+the added frame descriptor.
+In case of an error, these functions return
+.Dv DW_DLV_NOCOUNT
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Ar dbg
+or
+.Ar fde
+was NULL.
+.It Bq Er DW_DLE_ARGUMENT
+The frame descriptor referenced by argument

+.Pp
+DWARF attribute descriptors are represented by value of the opaque
+type
+.Vt Dwarf_Attribute ,

+.Pp
+Argument
+.Ar attr
+names the desired DWARF attribute.
+Legal values for argument

+constants in the DWARF specification.
+.Pp
+Argument
+.Ar atp
+points to a location into which the returned attribute descriptor
+will be written.
+The returned descriptor may then be passed to the form query functions in the
+.Xr dwarf 3
+API set to access the data associated with the attribute.
+.Pp
+If argument
+.Ar err
+is non-NULL, it will be used to return an error descriptor in case
+of an error.
+.Sh RETURN VALUES
+Function
+.Fn dwarf_attr
+returns
+.Dv DW_DLV_OK on success.
+.Pp
+If the debugging information entry descriptor denoted by argument
+.Ar die
+does not contain the named attribute, the function returns
+.Dv DW_DLV_NO_ENTRY
+and sets argument
+.Ar err .
+For other errors, it returns
+.Dv DW_DLV_ERROR
+and sets argument

+.Sh NAME
+.Nm dwarf_attrlist
+.Nd retrieve DWARF attribute descriptors
+.Sh LIBRARY
+.Lb libdwarf
+.Sh SYNOPSIS
+.In libdwarf.h
+.Ft int
+.Fo dwarf_attrlist
+.Fa "Dwarf_Die die"
+.Fa "Dwarf_Attribute **attrbuf"
+.Fa "Dwarf_Signed *attrcount"
+.Fa "Dwarf_Error *err"
+.Fc
+.Sh DESCRIPTION
+Function
+.Fn dwarf_attrlist
+retrieves the DWARF attribute descriptors associated with a
+debugging information entry descriptor in argument
+.Ar die .
+The descriptors are returned as an array of values of the opaque type
+.Vt Dwarf_Attribute .
+The data associated with each returned attribute descriptor may be
+queried using the form query functions in the
+.Xr dwarf 3
+API set.
+.Pp
+Argument
+.Ar attrbuf
+points to a location that will hold a pointer to the returned
+array of DWARF attribute descriptors.
+Argument
+.Ar attrcount
+points to a location that will hold the number of descriptors in
+the returned array.
+.Pp
+If argument
+.Ar err
+is non-NULL, it is used to return an error descriptor in case of an
+error.
+.Ss Memory Management
+In the current implementation, the memory allocated for each DWARF
+attribute descriptor and for the returned array of descriptors is
+managed by the library and the application does not need to explicitly
+free the returned pointers.
+However, for compatibility with other implementations of the
+.Xr dwarf 3
+API, the application is permitted to pass the pointers returned by to
+the
+.Fn dwarf_dealloc
+function.
+.Sh RETURN VALUES
+Function
+.Fn dwarf_attrlist
+returns
+.Dv DW_DLV_OK on success.
+.Pp
+If the debugging information entry descriptor denoted by argument
+.Ar die
+does not contain any attribute, the function returns
+.Dv DW_DLV_NO_ENTRY
+and sets argument
+.Ar err .
+For other errors, it returns
+.Dv DW_DLV_ERROR
+and sets argument
+.Ar err .
+.Sh EXAMPLES
+To retrieve the attribute list for a DWARF debugging information
+entry use:
+.Bd -literal -offset indent
+Dwarf_Die dw_die;
+Dwarf_Error dw_e;
+Dwarf_Unsigned dw_count;
+Dwarf_Attribute *dw_attributes;
+int error, i;
+
+\&... variable dw_die contains a reference to the DIE of interest ...
+
+/* Retrieve the attribute list from the DIE. */
+if ((error = dwarf_attrlist(dw_die, &dw_attributes, &dw_count,
+	&dw_e)) != DW_DLV_OK)
+	errx(EXIT_FAILURE, "dwarf_attrlist: %s", dwarf_errmsg(dw_e));
+
+/* Process the attribute list. */
+for (i = 0; i < dw_count; ++i) {
+	/* Use the returned pointers in dw_attributes[i] here. */
+}
+.Ed
+.Sh ERRORS
+Function
+.Fn dwarf_diename
+can fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+Arguments
+.Ar die ,
+.Ar attrbuf ,

+.It Bq Er DW_DLE_NO_ENTRY
+Argument
+.Ar die
+had no attributes.
+.It Bq Er DW_DLE_MEMORY
+An out of memory condition was encountered during the execution of the
+function.

+.Sh DESCRIPTION
+These functions search the debugging information entry referenced
+by argument
+.Ar die
+for the attribute named by argument
+.Ar attr .
+If the named attribute is found, the functions set the location
+pointed to by argument
+.Ar ret
+to the value of the attribute.
+The argument
+.Ar err ,
+if non NULL,
+will be used to return an error descriptor in case of an error.
+.Pp
+Function
+.Fn dwarf_attrval_flag
+sets the location pointed to by argument
+.Ar ret
+to either 0 or 1. If the form of the attribute named by argument
+.Ar attr
+is
+.Dv DW_FORM_flag ,
+function
+.Fn dwarf_attrval_flag
+sets the location pointed to by argument
+.Ar ret
+to 1 if the attribute has a non-zero value, or to 0 otherwise.
+If the form of the attribute named by argument
+.Ar attr
+is
+.Dv DW_FORM_flag_present ,
+function
+.Fn dwarf_attrval_flag
+unconditionally sets the location pointed to by argument
+.Ar ret
+to 1.
+The form of the attribute must be one of
+.Dv DW_FORM_flag
+or
+.Dv DW_FORM_flag_present .
+.Pp
+Function
+.Fn dwarf_attrval_signed
+stores the value for the attribute named by argument
+.Ar attr ,
+into the location pointed to by argument
+.Ar ret .
+The attribute's value is treated as a signed integral quantity and is
+sign-extended as needed.
+The attribute named by the argument
+.Ar attr
+must belong to the
+.Dv CONSTANT
+class and must have one of the following forms:
+.Dv DW_FORM_data1 ,
+.Dv DW_FORM_data2 ,
+.Dv DW_FORM_data4 ,
+.Dv DW_FORM_data8
+or
+.Dv DW_FORM_sdata .
+.Pp
+Function
+.Fn dwarf_attrval_string
+sets the location pointed to by argument
+.Ar ret
+to a pointer to a NUL-terminated string that is the value of the
+attribute named by argument
+.Ar attr .
+The form of the attribute must be one of
+.Dv DW_FORM_string
+or
+.Dv DW_FORM_strp .
+.Pp
+Function
+.Fn dwarf_attrval_unsigned
+stores the value for the attribute named by argument
+.Ar attr
+into the location pointed to by argument
+.Ar ret .
+The attribute's value is treated as an unsigned integral quantity, and
+is zero-extended as needed.
+The named attribute must belong to one of the
+.Dv CONSTANT ,
+.Dv ADDRESS
+or
+.Dv REFERENCE
+classes and must have one of the following forms:
+.Dv DW_FORM_addr ,
+.Dv DW_FORM_data1 ,
+.Dv DW_FORM_data2 ,
+.Dv DW_FORM_data4 ,
+.Dv DW_FORM_data8 ,
+.Dv DW_FORM_udata ,

+.Dv DW_FORM_ref2 ,
+.Dv DW_FORM_ref4 ,
+.Dv DW_FORM_ref8 ,
+or
+.Dv DW_FORM_ref_udata .
+.Pp
+If the attribute named by argument
+.Ar attr
+is
+.Dv DW_AT_type
+and is not present in the debugging information entry referenced by argument
+.Ar die ,
+and if a
+.Dv DW_AT_abstract_origin
+or
+.Dv DW_AT_specification
+attribute is present in the debugging information entry,
+function
+.Fn dwarf_attrval_unsigned
+will search for the named attribute in the debugging information entry
+referenced by the
+.Dv DW_AT_abstract_origin
+or
+.Dv DW_AT_specification
+attribute.
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+If the named attribute was not found in the specified debugging
+information entry descriptor these functions return
+.Dv DW_DLV_NO_ENTRY
+and set argument
+.Ar err .
+For other errors, these functions return
+.Dv DW_DLV_ERROR
+and set argument
+.Ar err .
+.Sh COMPATIBILITY
+These functions are extensions added by this implementation of the
+DWARF(3) API.
+.Sh ERRORS
+These functions may fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_ATTR_FORM_BAD"
+.It Bq Er DW_DLE_ARGUMENT
+Either of the arguments

+.Sh DESCRIPTION
+These functions are used to retrieve and traverse DWARF
+Debugging Information Entry (DIE) descriptors associated with
+a compilation unit.
+These descriptors are arranged in the form of a tree, traversable
+using
+.Dq child
+and
+.Dq sibling
+links; see
+.Xr dwarf 3
+for more information.
+DWARF Debugging Information Entry descriptors are represented
+by the
+.Vt Dwarf_Die
+opaque type.
+.Pp
+Function
+.Fn dwarf_child
+retrieves the child of descriptor denoted by argument
+.Ar die ,
+and stores it in the location pointed to by argument
+.Ar ret_die .
+.Pp
+Function
+.Fn dwarf_siblingof
+retrieves the sibling of the descriptor denoted by argument
+.Ar die ,
+and stores it in the location pointed to by argument
+.Ar ret_die .
+If argument
+.Ar die
+is NULL, the first debugging information entry descriptor for the
+current compilation unit will be returned.
+This function and function
+.Fn dwarf_child
+may be used together to traverse the tree of debugging information
+entry descriptors for a compilation unit.
+.Pp
+Function
+.Fn dwarf_siblingof_b
+is identical to the function
+.Fn dwarf_siblingof
+except that it can retrieve the sibling descriptor from either the
+current compilation unit or type unit.
+If argument
+.Ar is_info
+is non-zero, the function behaves identically to function
+.Fn dwarf_siblingof .
+If argument
+.Ar is_info
+is zero, the descriptor referred by argument
+.Ar die
+should be associated with a debugging information entry in the
+type unit.
+The function will store the sibling of the descriptor in the location
+pointed to by argument
+.Ar ret_die .
+If argument
+.Ar is_info
+is zero and argument
+.Ar die
+is
+.Dv NULL ,
+the first debugging information entry descriptor for the
+current type unit will be returned.
+.Pp
+Function
+.Fn dwarf_offdie
+retrieves the debugging information entry descriptor at global offset
+.Ar offset
+in the
+.Dq .debug_info
+section of the object associated with argument
+.Ar dbg .
+The returned descriptor is written to the location pointed to by argument
+.Ar ret_die .
+.Pp
+Function
+.Fn dwarf_offdie_b
+is identical to the function
+.Fn dwarf_offdie
+except that it can retrieve the debugging information entry descriptor at
+global offset
+.Ar offset
+from either of the
+.Dq .debug_info
+and
+.Dq .debug_types
+sections of the object associated with argument
+.Ar dbg .
+If argument
+.Ar is_info
+is non-zero, the function will retrieve the debugging information
+entry from the
+.Dq .debug_info
+section, otherwise the function will retrieve the debugging
+information entry from the
+.Dq .debug_types
+section.
+The returned descriptor is written to the location pointed to by argument
+.Ar ret_die .
+.Ss Memory Management
+The memory area used for the
+.Vt Dwarf_Die
+descriptor returned in argument
+.Ar ret_die
+is allocated by the
+.Lb libdwarf .
+Application code should use function
+.Fn dwarf_dealloc
+with the allocation type
+.Dv DW_DLA_DIE
+to free the memory area when the
+.Vt Dwarf_Die
+descriptor is no longer needed.
+.Sh RETURN VALUES
+These functions return the following values:
+.Bl -tag -width ".Bq Er DW_DLV_NO_ENTRY"
+.It Bq Er DW_DLV_OK
+The call succeeded.
+.It Bq Er DW_DLV_ERROR
+The requested operation failed.
+Additional information about the error encountered will be recorded in
+argument
+.Ar err ,
+if it is not NULL.
+.It Bq Er DW_DLV_NO_ENTRY
+For functions
+.Fn dwarf_child ,
+.Fn dwarf_siblingof
+and
+.Fn dwarf_siblingof_b ,
+the descriptor denoted by argument
+.Ar die
+did not have a child or sibling.
+.Pp
+For functions
+.Fn dwarf_offdie
+and
+.Fn dwarf_offdie_b ,
+there was no debugging information entry at the offset specified by
+argument
+.Ar offset .
+.El
+.Sh ERRORS
+These functions may fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_DIE_NO_CU_CONTEXT"
+.It Bq Er DW_DLE_ARGUMENT
+Arguments
+.Ar dbg ,
+.Ar die
+or
+.Ar ret_die
+were NULL.
+.It Bq Er DW_DLE_DIE_NO_CU_CONTEXT
+Argument
+.Ar dbg
+was not associated with a compilation unit.
+.It Bq Er DW_DLE_NO_ENTRY
+The descriptor denoted by argument
+.Ar die
+had no child or sibling, or there was no DWARF debugging information
+entry at the offset specified by argument
+.Va offset .
+.El
+.Sh EXAMPLES
+To retrieve the first DWARF Debugging Information Entry descriptor for
+the first compilation unit associated with a
+.Vt Dwarf_Debug
+instance, and to traverse all its children, use:
+.Bd -literal -offset indent
+Dwarf_Debug dbg;
+Dwarf_Die die, die0;
+Dwarf_Error de;
+
+\&... allocate dbg using dwarf_init() etc ...
+
+if (dwarf_next_cu_header(dbg, NULL, NULL, NULL, NULL, NULL, &de) !=
+    DW_DLV_OK)
+	errx(EXIT_FAILURE, "dwarf_next_cu_header: %s",
+	    dwarf_errmsg(de));
+
+/* Get the first DIE for the current compilation unit. */
+die = NULL;
+if (dwarf_siblingof(dbg, die, &die0, &de) != DW_DLV_OK)
+	errx(EXIT_FAILURE, "dwarf_siblingof: %s", dwarf_errmsg(de));

+.Sh DESCRIPTION
+The function
+.Fn dwarf_dealloc
+is used by applications to indicate that memory areas returned by
+.Lb libdwarf
+may be safely disposed off.
+Due to the way memory is managed in the current implementation, the
+use of
+.Fn dwarf_dealloc
+is only necessary for a small set of DWARF types.
+.Pp
+Argument
+.Ar dbg
+should reference a valid debugging context allocated using
+.Xr dwarf_init 3 .
+.Pp
+Argument
+.Ar ptr
+should point to an object or memory area obtained by a prior call
+to a DWARF(3) function.
+.Pp
+Argument
+.Ar type
+indicates the type of object being deallocated.
+The indicated type must match that of the object being passed in
+argument
+.Ar ptr .
+Valid values for the
+.Ar type
+argument are:
+.Bl -tag -width ".Dv DW_DLA_FRAME_BLOCK"
+.It Dv DW_DLA_ABBREV
+An object of type
+.Vt Dwarf_Abbrev ,
+as returned by a call to the function
+.Xr dwarf_get_abbrev 3 .
+.It Dv DW_DLA_DIE
+An object of type
+.Vt Dwarf_Die ,
+as returned by calls to the functions
+.Xr dwarf_child 3 ,
+.Xr dwarf_offdie 3
+or
+.Xr dwarf_siblingof 3 .
+.It Dv DW_DLA_FRAME_BLOCK
+An array of objects of type
+.Vt Dwarf_Frame_op ,
+as returned by a call to the function
+.Xr dwarf_expand_frame_instructions 3 .
+.El
+.Pp
+Calls to
+.Fn dwarf_dealloc
+with other values for argument
+.Ar type
+are no-ops in this implementation.
+.Pp
+The functions
+.Fn dwarf_fde_cie_list_dealloc ,
+.Fn dwarf_funcs_dealloc ,
+.Fn dwarf_globals_dealloc ,
+.Fn dwarf_pubtypes_dealloc ,
+.Fn dwarf_ranges_dealloc ,
+.Fn dwarf_srclines_dealloc ,
+.Fn dwarf_types_dealloc ,
+.Fn dwarf_vars_dealloc
+and
+.Fn dwarf_weaks_dealloc
+are provided for compatibility with other implementations of the
+DWARF(3) API.
+Due to the way memory is managed in the current implementation, these
+functions are effectively no-ops.
+.Pp
+See
+.Xr dwarf 3
+for more information about the memory management scheme in this
+implementation of the DWARF(3) API.

+.Sh DESCRIPTION
+Function
+.Fn dwarf_def_macro
+adds a macro definition to a DWARF producer instance.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF producer instance allocated using
+.Xr dwarf_producer_init 3
+or
+.Xr dwarf_producer_init_b 3 .
+.Pp
+Argument
+.Ar lineno
+specifies the line number of the source line where the macro is
+defined.
+A line number of zero is used for macros that are defined
+before any source file is read.
+.Pp
+Argument
+.Ar name
+should point to a NUL-terminated string containing the name
+of the macro.
+For function-like macros this parameter should also include
+parentheses and parameter names if any.
+.Pp
+Argument
+.Ar value
+should point to a NUL-terminated string containing the value
+of the macro.
+If the macro does not have a value, argument
+.Ar value
+should be set to NULL.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Sh RETURN VALUES
+On success, function
+.Fn dwarf_def_macro

+.Sh DESCRIPTION
+The
+.Fn dwarf_finish
+and
+.Fn dwarf_object_finish
+functions are used to release the resources associated with a debug
+descriptor allocated by a prior call to
+.Xr dwarf_init 3
+and
+.Xr dwarf_object_init 3
+respectively.
+.Pp
+Argument
+.Ar dbg
+denotes a valid

+.Ar err
+will be used to record error information in case of an error.
+.Pp
+After a call to
+.Fn dwarf_finish

+will be invalid and should not be used further.
+.Pp
+For
+.Vt Dwarf_Debug
+descriptors opened using

+the application would need to explicitly release the
+.Vt Elf

+.Sh RETURN VALUES
+These functions return

+.Sh DESCRIPTION
+Function
+.Fn dwarf_get_abbrev
+retrieves information about an abbreviation from the DWARF abbreviations
+section,
+.Dq ".debug_abbrev" .
+Abbreviation information is returned using an opaque descriptor
+of type
+.Vt Dwarf_Abbrev .
+The returned
+.Vt Dwarf_Abbrev
+descriptor may then be passed to the other abbreviation related APIs
+in the DWARF(3) API to retrieve specific information about the
+abbreviation.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF debug context allocated using
+.Xr dwarf_init 3 .
+.Pp
+Argument
+.Ar offset
+should be an offset, relative to the
+.Dq ".debug_abbrev"
+section, to the start of an abbreviation entry.
+.Pp
+Argument
+.Ar ret_abbrev
+should point to a location that will hold a pointer to the
+returned
+.Vt Dwarf_Abbrev
+descriptor.
+.Pp
+Argument
+.Ar length
+should point to a location that will hold the number of bytes used
+by the abbrevation in the DWARF
+.Dq ".debug_abbrev"
+section.
+.Pp
+Argument
+.Ar attr_count
+should point to a location that will hold the number of
+attributes in the abbrevation.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Ss Memory Management
+The memory area used for the
+.Vt Dwarf_Abbrev
+descriptor returned in argument
+.Ar ret_abbrev
+is allocated by the
+.Lb libdwarf .
+Application code should use function
+.Fn dwarf_dealloc
+with the allocation type
+.Dv DW_DLA_ABBREV
+to free the memory area when the
+.Vt Dwarf_Abbrev
+descriptor is no longer needed.
+.Ss Application Programming Notes
+The last abbreviation entry in a standard DWARF abbreviation section
+will have a special length value of 1.
+.Sh RETURN VALUES
+Function
+.Fn dwarf_get_abbrev
+returns
+.Dv DW_DLV_OK
+when it succeeds.
+It returns
+.Dv DW_DLV_NO_ENTRY
+if there is no abbreviation information at offset
+.Ar offset .
+In case of an error, it returns

+.Sh DESCRIPTION
+These functions retrieve frame related information for the specified
+DWARF debug context.
+.Pp
+Function
+.Fn dwarf_get_fde_list
+retrieves frame information from the DWARF section named
+.Dq ".debug_frame" .
+For objects containing GNU style C++ exception handling
+information, the function
+.Fn dwarf_get_fde_list_eh
+retrieves frame information from the section named
+.Dq ".eh_frame" .
+.Pp
+Frame information is returned using opaque descriptors
+of type
+.Vt Dwarf_Cie
+and
+.Vt Dwarf_Fde .
+Applications need to use the other frame related functions in the
+DWARF(3) API set to retrieve the information contained in these
+descriptors.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF debug context allocated using
+.Xr dwarf_init 3 .
+.Pp
+Argument
+.Ar cie_list
+should point to a location that will be set to a pointer to an array
+of
+.Vt Dwarf_Cie
+descriptors.
+.Pp
+Argument
+.Ar cie_count
+should point to a location that will be set to the number of
+.Vt Dwarf_Cie
+descriptors returned.
+.Pp
+Argument
+.Ar fde_list
+should point to a location that will be set to a pointer to an array
+of
+.Vt Dwarf_Fde
+descriptors.
+.Pp
+Argument
+.Ar fde_count
+should point to a location that will be set to the number of
+.Vt Dwarf_Fde
+descriptors returned.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Ss Memory Management
+The memory areas used for the arrays returned in arguments
+.Ar cie_list
+and
+.Ar fde_list
+are owned by the
+.Lb libdwarf .
+Application code should not attempt to directly free these areas.
+Portable applications should instead use the
+.Xr dwarf_fde_cie_list_dealloc 3
+function to indicate that these memory areas may be freed.
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+They return
+.Dv DW_DLV_NO_ENTRY
+if there is no frame information associated with the given DWARF
+debug context.
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions may fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Va dbg ,
+.Va cie_list ,
+.Va cie_count ,
+.Va fde_list

+.Sh DESCRIPTION
+These functions retrieve information about file-scope, user-defined
+types recorded in lookup tables in the
+.Dq ".debug_pubtypes"
+DWARF section.
+Information about these types is returned using opaque descriptors
+of type
+.Vt Dwarf_Type .
+Applications need to use the functions described below to retrieve
+the name and offset information contained in these descriptors.
+.Pp
+Function
+.Fn dwarf_get_pubtypes
+retrieves descriptors for all the user-defined types associated with the
+DWARF debug context specified by argument
+.Ar dbg .
+The argument
+.Ar types
+should point to a location that will be set to a pointer to an array
+of
+.Vt Dwarf_Type
+descriptors.
+The argument
+.Ar ntypes
+should point to a location that will be set to the number of
+descriptors returned.
+.Pp
+Function
+.Fn dwarf_pubtype_cu_offset
+returns the offset, relative to the
+.Dq ".debug_info"
+section, of the compilation unit that contains the debugging
+information entry associated with the argument
+.Ar type .
+Argument
+.Ar cu_offset
+should point to a location that will hold the returned offset.
+.Pp
+Function
+.Fn dwarf_pubtype_die_offset
+retrieves the offset, relative to the
+.Dq ".debug_info"
+section, of the debugging information entry associated with the
+argument
+.Ar type ,
+and stores it into the location pointed to by the argument
+.Ar die_offset .
+.Pp
+Function
+.Fn dwarf_pubtype_name_offsets
+retrieves the name and offsets for the debugging information entry for
+argument
+.Ar type .
+Argument
+.Ar name
+should point to a location which will be set to a pointer to a
+NUL-terminated string containing the name of the associated debugging
+information entry.
+Argument
+.Ar die_offset
+should point to a location which will be set to the
+offset, relative to the
+.Dq ".debug_info"
+section, of the associated debugging information entry.
+Argument
+.Ar cu_die_offset
+should point to a location which will be set to the
+offset, relative to the
+.Dq ".debug_info"
+section, of the first debugging information entry in the compilation
+unit associated with argument
+.Ar type .
+.Pp
+Function
+.Fn dwarf_pubtypename
+sets the location pointed to by argument
+.Ar name
+to a pointer to a NUL-terminated string holding the name of the
+debugging information entry associated with the argument
+.Ar type .
+.Ss Memory Management
+The memory area used for the array of
+.Vt Dwarf_Type
+descriptors returned in argument
+.Ar types
+by function
+.Fn dwarf_get_pubtypes
+is owned by the
+.Lb libdwarf .
+Application code should not attempt to directly free this pointer.
+Portable code should instead use the function
+.Xr dwarf_types_dealloc 3
+to indicate that the memory area may be freed.
+.Pp
+The memory area used for the string returned in the
+.Ar name
+argument to functions
+.Fn dwarf_pubtype_name_offsets
+and
+.Fn dwarf_pubtypename
+is owned by the
+.Lb libdwarf .
+Portable code should indicate that the memory area can
+be freed using the
+.Xr dwarf_dealloc 3
+function.
+.Ss Error Returns
+If argument
+.Ar err
+is not NULL, these functions will use it to store error information,
+in case of an error.
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh EXAMPLES
+To retrieve the list of file scope user-defined types and print
+their names, use:
+.Bd -literal -offset indent
+Dwarf_Debug dbg;
+Dwarf_Signed ntypes;
+Dwarf_Type *types;
+Dwarf_Error err;
+int n, result;
+char *typename;
+
+/* Initialize dbg etc. */;
+result = dwarf_get_pubtypes(dbg, &types, &ntypes, &err);
+if (result != DW_DLV_OK) /* Handle the error. */

+
+/* Iterate over the returned array of descriptors. */
+for (n = 0; n < ntypes; n++) {
+	result = dwarf_pubtypename(types[n], &typename, &err);
+	if (result != DW_DLV_OK) /* Handle the error. */
+		;
+	printf("%s\en", typename);
+}
+
+/* Deallocate the returned array. */
+dwarf_types_dealloc(dbg, types, ntypes);

+.Sh DESCRIPTION
+Function
+.Fn dwarf_get_ranges
+retrieves information about the non-contiguous address ranges associated
+with a DWARF debugging information entry.
+Information about address ranges is returned as an array of
+descriptors of type
+.Vt Dwarf_Ranges ,
+with each
+.Vt Dwarf_Ranges
+descriptor describing one address range entry.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF debug context allocated using
+.Xr dwarf_init 3 .
+.Pp
+Argument
+.Ar offset
+is an offset, relative to the
+.Dq ".debug_ranges"
+section, to the start of the desired list of address ranges.
+The offset of an address ranges list is indicated by the
+.Dv DW_AT_ranges
+attribute of a debugging information entry.
+.Pp
+Argument
+.Ar die
+(function
+.Fn dwarf_get_ranges_a
+only) is ignored in this implementation; see the section
+.Sx "Compatibility Notes"
+below.
+.Pp
+Argument
+.Ar ranges
+should point to a location that will be set to a pointer to an array
+of
+.Vt Dwarf_Ranges
+descriptors.
+.Pp
+Argument
+.Ar cnt
+should point to a location that will be set to the number of entries
+returned.
+If argument
+.Ar byte_cnt
+is not NULL, it will be set to the number of bytes occupied by the
+returned entries in the
+.Dq ".debug_ranges"
+section.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case
+of an error.
+.Pp
+.Vt Dwarf_Ranges
+descriptors are defined in the header file
+.In libdwarf.h ,
+and consists of the following fields:
+.Bl -tag -width ".Va dwr_addr1"
+.It Va dwr_addr1
+The first address offset, whose meaning depends on the type of the
+entry.
+.It Va dwr_addr2
+The second address offset, whose meaning depends on the type of the
+entry.
+.It Va dwr_type
+The type of this address range entry:
+.Bl -tag -width ".Dv DW_RANGES_ENTRY" -compact
+.It Dv DW_RANGES_ENTRY
+A range list entry.
+For this type of entry, the fields
+.Va dwr_addr1
+and
+.Va dwr_addr2
+hold the beginning and ending offsets of the address range, respectively.
+.It Dv DW_RANGES_ADDRESS_SELECTION
+A base address selection entry.
+For this type of entry, the field
+.Va dwr_addr1
+is the value of the largest representable address offset, and
+.Va dwr_addr2
+is a base address for the beginning and ending address offsets of
+subsequent address range entries in the list.
+.It Dv DW_RANGES_END
+An end of list mark.
+Both
+.Va dwr_addr1
+and
+.Va dwr_addr2
+are set to 0.
+.El
+.El
+.Ss Memory Management
+The memory area used for the array of
+.Vt Dwarf_Ranges
+descriptors returned in argument
+.Ar ranges
+is owned by the
+.Lb libdwarf .
+The application should not attempt to directly free this pointer.
+Portable code should instead use
+.Fn dwarf_ranges_dealloc
+to indicate that the memory may be freed.
+.Sh COMPATIBILITY
+Function
+.Fn dwarf_get_ranges_a
+is identical to
+.Fn dwarf_get_ranges ,
+except that it requires one additional argument
+.Ar die
+denoting the debugging information entry associated with
+the address range list.
+In this implementation of the
+.Lb libdwarf ,
+the argument
+.Ar die
+is ignored, and function
+.Fn dwarf_get_ranges_a
+is only provided for compatibility with other implementations of the
+DWARF(3) API.
+.Sh RETURN VALUES
+These functions
+return
+.Dv DW_DLV_OK
+when they succeed.
+They return
+.Dv DW_DLV_NO_ENTRY
+if there is no address range list at the specified offset
+.Ar offset .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These function can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_NO_ENTRY"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Ar dbg ,
+.Ar ranges
+or
+.Ar cnt
+was NULL.
+.It Bq Er DW_DLE_NO_ENTRY
+There is no address range list at the specified offset
+.Ar offset .
+.El
+.Sh EXAMPLE
+To retrieve the address range list associated with a debugging
+information entry, use:
+.Bd -literal -offset indent
+Dwarf_Debug dbg;
+Dwarf_Die die;
+Dwarf_Error de;
+Dwarf_Addr base;
+Dwarf_Attribute *attr_list;
+Dwarf_Ranges *ranges;
+Dwarf_Signed cnt;

+.Pp
+Each call to function
+.Fn dwarf_get_section_bytes
+will return the byte stream for one ELF section.
+The first call to this function will always return the first ELF
+section, and the subsequent calls will return the rest of sections
+in the order when they were generated, until the last one.
+The total number of sections generated is returned by the function
+.Xr dwarf_transform_to_disk_form 3 .
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF producer instance allocated using the
+functions
+.Xr dwarf_producer_init 3
+or

+.Pp
+Argument
+.Ar dwarf_section
+is currently ignored.
+.Pp
+Argument
+.Ar elf_section_index
+should point to a location which will be set to the section index value
+of the returned ELF section.
+.Pp
+Argument
+.Ar length
+should point to a location which will hold the length in bytes of the
+returned ELF section.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Ss Memory Management
+The memory areas used for the returned ELF section byte streams should
+be freed using the function
+.Fn dwarf_producer_finish .
+.Sh RETURN VALUES
+On success, function
+.Fn dwarf_get_section_bytes
+returns a pointer to a ELF section byte stream.
+In case of an error, function
+.Fn dwarf_get_section_bytes
+will return NULL and set the argument
+.Ar err .
+.Sh ERRORS
+Function
+.Fn dwarf_get_section_bytes
+can fail with:

+These APIs retrieve information about user-defined types from the
+SGI-specific
+.Dq ".debug_typenames"
+section.
+.Pp
+Standards-conformant applications should use the functions
+.Xr dwarf_get_pubtypes 3 ,
+.Xr dwarf_pubtype_cu_offset 3 ,
+.Xr dwarf_pubtype_die_offset 3 ,
+.Xr dwarf_pubtype_name_offsets 3
+and
+.Xr dwarf_pubtypename 3 ,
+which operate on the equivalent
+.Dq ".debug_pubtypes"
+section defined by the DWARF3 standard.
+.Pp
+Information about user-defined types is returned using opaque descriptors
+of type
+.Vt Dwarf_Type .
+Applications need to use the functions described below to retrieve
+the name and offset information contained in these descriptors.
+.Pp
+Function
+.Fn dwarf_get_types
+retrieves descriptors for all user-defined types associated with the
+DWARF debug context specified by argument
+.Ar dbg .
+The argument
+.Ar types
+should point to a location that will be set to a pointer to an array
+of
+.Vt Dwarf_Type
+descriptors.
+The argument
+.Ar ntypes
+should point to a location that will be set to the number of
+descriptors returned.
+.Pp
+Function
+.Fn dwarf_type_cu_offset
+returns the offset, relative to the
+.Dq ".debug_info"
+section, of the compilation unit that contains the debugging
+information entry associated with the argument
+.Ar type .
+Argument
+.Ar cu_offset
+should point to a location that will hold the returned offset.
+.Pp
+Function
+.Fn dwarf_type_die_offset
+retrieves the offset, relative to the
+.Dq ".debug_info"
+section, of the debugging information entry associated with the
+argument
+.Ar type ,
+and stores it into the location pointed to by the argument
+.Ar die_offset .
+.Pp
+Function
+.Fn dwarf_type_name_offsets
+retrieves the name and offsets for the debugging information
+entry for argument
+.Ar type .
+Argument
+.Ar name
+should point to a location which will be set to a pointer to a
+NUL-terminated string containing the name of the associated debugging
+information entry.
+Argument
+.Ar die_offset
+should point to a location which will be set to the offset, relative
+to the
+.Dq ".debug_info"
+section, of the associated debugging information entry.
+Argument
+.Ar cu_die_offset
+should point to a location which will be set to a offset, relative to
+the
+.Dq ".debug_info"
+section, of the first debugging information entry in the compilation
+unit associated with argument
+.Ar type .
+.Pp
+Function
+.Fn dwarf_typename
+sets the location pointed to by argument
+.Ar name
+to a pointer to a NUL-terminated string holding the name of the
+debugging information entry associated with the argument
+.Ar type .
+.Ss Memory Management
+The memory area used for the array of
+.Vt Dwarf_Type
+descriptors returned in argument
+.Ar types
+by function
+.Fn dwarf_get_types
+is owned by the
+.Lb libdwarf .
+Application code should not attempt to directly free this pointer.
+Portable code should instead use the function

+These functions retrieve information about the file scope static
+variables associated with a DWARF debug context.
+Information about these static variables is returned using opaque
+descriptors of type
+.Vt Dwarf_Var .
+Applications need to use the functions described below to retrieve
+the name and offset information contained in these descriptors.
+.Pp
+Function
+.Fn dwarf_get_vars
+retrieves descriptors for all the static variables associated with the
+DWARF debug context specified by argument
+.Ar dbg .
+The argument
+.Ar vars
+should point to a location that will be set to a pointer to an array
+of

+.Sh DESCRIPTION
+These functions allocate and return a
+.Vt Dwarf_Debug
+instance for the object denoted by argument
+.Ar fd
+or
+.Ar elf .
+This instance would be used for subsequent access to debugging information in the object by other functions in the DWARF(3) library.
+.Pp
+For function
+.Fn dwarf_init ,
+argument
+.Ar fd
+denotes an open file descriptor referencing a compilation object.
+Function
+.Fn dwarf_init
+implicitly allocates an
+.Vt Elf
+descriptor for argument
+.Ar fd .
+.Pp
+For function
+.Fn dwarf_elf_init ,
+argument
+.Ar elf
+denotes a descriptor returned by
+.Xr elf_begin 3
+or
+.Xr elf_memory 3 .
+.Pp
+Argument
+.Ar mode
+specifies the access mode desired.
+It should be at least as permissive as the mode with which
+the file descriptor
+.Ar fd
+or the ELF descriptor
+.Ar elf
+was created with.
+Legal values for argument
+.Ar mode
+are:
+.Pp
+.Bl -tag -width "DW_DLC_WRITE" -compact
+.It DW_DLC_RDWR
+Permit reading and writing of DWARF information.
+.It DW_DLC_READ
+Operate in read-only mode.
+.It DW_DLC_WRITE
+Permit writing of DWARF information.
+.El
+.Pp
+Argument
+.Ar errhand
+denotes a function to be called in case of an error.
+If this argument is
+.Dv NULL
+then a default error handling scheme is used.
+See
+.Xr dwarf 3
+for a description of the error handling scheme used by the
+DWARF(3) library.
+.Pp
+Argument
+.Ar errarg
+is passed to the error handler function denoted by argument
+.Ar errhand
+when it is invoked.
+.Pp
+Argument
+.Ar ret
+points to the memory location that will hold a
+.Vt Dwarf_Debug
+reference on a successful call these functions.
+.Pp
+Argument
+.Ar err
+references a memory location that would hold a
+.Vt Dwarf_Error
+descriptor in case of an error.
+.Ss Memory Management
+The
+.Vt Dwarf_Debug
+instance returned by these functions should be freed using
+.Fn dwarf_finish .
+.Sh RETURN VALUES
+These functions return the following values:
+.Bl -tag -width ".Bq Er DW_DLV_NO_ENTRY"
+.It Bq Er DW_DLV_OK
+This return value indicates a successful return.
+.It Bq Er DW_DLV_ERROR
+The operation failed.
+.It Bq Er DW_DLV_NO_ENTRY
+The object specified by arguments
+.Ar "fd"
+or
+.Ar "elf"
+did not contain debug information.
+.El
+.Sh IMPLEMENTATION NOTES
+The current implementation does not support access modes
+.Dv DW_DLC_RDWR
+and
+.Dv DW_DLC_WRITE .
+.Sh EXAMPLES
+To initialize a
+.Vt Dwarf_Debug
+instance from a open file descriptor referencing an ELF object, and
+with the default error handler, use:
+.Bd -literal -offset indent
+Dwarf_Error err;
+Dwarf_Debug dbg;
+
+if (dwarf_init(fd, DW_DLC_READ, NULL, NULL, &dbg, &err) !=
+    DW_DLV_OK)
+	errx(EXIT_FAILURE, "dwarf_init: %s", dwarf_errmsg(err));

+.Sh DESCRIPTION
+These functions retrieve specific line information associated with
+the line descriptor specified by argument
+.Ar ln ,
+and stores it in the location pointed to by argument
+.Ar ret .
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Pp
+Function
+.Fn dwarf_lineaddr
+stores the program address corresponding to the source line specified
+in argument
+.Ar ln
+into the location pointed to by argument
+.Ar ret .
+.Pp
+Function
+.Fn dwarf_linebeginstatement
+sets the location pointed to by argument
+.Ar ret
+to 1 if the source line specified by the line descriptor
+.Ar ln
+is the beginning of a statement, or to 0 otherwise.
+.Pp
+Function
+.Fn dwarf_lineblock
+sets the location pointed to by argument
+.Ar ret
+to 1 if the source line specified by the line descriptor
+.Ar ln
+is the beginning of a basic block, or to 0 otherwise.
+.Pp
+Function
+.Fn dwarf_lineendsequence
+sets the location pointed to by argument
+.Ar ret
+to 1 if the program address associated with the line descriptor
+.Ar ln
+is the address immediately following the end of a sequence of target
+machine instructions, or to 0 otherwise.
+.Pp
+Function
+.Fn dwarf_lineno
+stores the line number of the source line associated with the line
+descriptor
+.Ar ln
+into the location pointed to by argument
+.Ar ret .
+.Pp
+Function
+.Fn dwarf_lineoff
+stores the column number within a line associated with descriptor
+.Ar ln
+into the location pointed to by argument
+.Ar ret .
+The retrieved column numbers are 1-based, with the value -1 indicating
+that column number information was not available.
+.Pp
+Function
+.Fn dwarf_linesrc
+stores a pointer to a NUL-terminated string containing the source file
+name associated with line descriptor
+.Ar ln
+into the location pointed to by argument
+.Ar ret .
+The full path of the source file is returned if possible.
+The memory used for the source file name string is managed by the DWARF(3)
+library and should not be directly freed by application code.
+Instead, portable code should use
+.Xr dwarf_dealloc 3
+to indicate that the string should be freed.
+.Pp
+Function
+.Fn dwarf_line_srcfileno
+stores the index of the source file associated with the line descriptor
+.Ar ln
+in the location pointed to by argument
+.Ar ret .
+The returned value is 1-based index into the array of source file
+names returned by
+.Xr dwarf_srcfiles 3 .
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions may fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_LINE_FILE_NUM_BAD"
+.It Bq Er DW_DLE_ARGUMENT
+Either of the arguments
+.Va ln
+or
+.Va ret
+was NULL.
+.It Bq Er DW_DLE_LINE_FILE_NUM_BAD
+The source file name associated with the line descriptor
+.Ar ln
+could not be retrieved by function

+.Sh DESCRIPTION
+These functions retrieve the location expressions
+associated with a DWARF attribute.
+.Pp
+Note: function
+.Fn dwarf_loclist
+is deprecated.
+New application code should instead use function
+.Fn dwarf_loclist_n
+.Pp
+Function
+.Fn dwarf_loclist_n
+retrieves the list of location expressions associated with a DWARF
+attribute.
+Argument
+.Ar at
+should reference a valid DWARF attribute.
+Argument
+.Ar llbuf
+should point to a location which will hold a returned array of
+pointers to
+.Vt Dwarf_Locdesc
+descriptors.
+Argument
+.Ar listlen
+should point to a location which will be set to the number of
+elements contained in the returned array.
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case

+.Pp
+Function
+.Fn dwarf_loclist
+retrieves the first location expression associated with an attribute.
+Argument
+.Ar at
+should reference a valid DWARF attribute.
+Argument
+.Ar llbuf
+should point to a location which will hold the returned pointer
+to a
+.Vt Dwarf_Locdesc
+descriptor.
+Argument
+.Ar listlen
+should point to a location which will be always set to 1.
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case
+of an error.
+.Pp
+.Vt Dwarf_Locdesc
+descriptors are defined in the header file
+.In libdwarf.h ,
+and consist of following fields:
+.Pp
+.Bl -tag -width ".Va ld_cents" -compact
+.It Va ld_lopc
+The lowest program counter address covered by the descriptor.
+This field will be set to 0 if the descriptor is not associated with
+an address range.
+.It Va ld_hipc
+The highest program counter address covered by the descriptor.
+This field will be set to 0 if the descriptor is not associated with
+an address range.
+.It Va ld_cents
+The number of entries returned in
+.Va ld_s
+field.
+.It Va ld_s
+Pointer to an array of
+.Vt Dwarf_Loc
+descriptors.
+.El
+.Pp
+Each
+.Vt Dwarf_Loc
+descriptor represents one operation of a location expression.
+These descriptors are defined in the header file
+.In libdwarf.h ,
+and consist of following fields:
+.Pp
+.Bl -tag -width ".Va lr_number2" -compact
+.It Va lr_atom
+The operator name, one of the
+.Dv DW_OP_*
+constants defined in the header file
+.In dwarf.h .
+.It Va lr_number
+The first operand of this operation.
+.It Va lr_number2
+The second operand of this operation.
+.It Va lr_offset
+The byte offset of this operation within the containing location
+expression.
+.El
+.Ss Memory Management
+The memory area used for the descriptor array returned in argument
+.Ar llbuf
+is allocated by the
+.Lb libdwarf .
+When the descriptor array is no longer needed, application code should
+use function
+.Xr dwarf_dealloc 3
+to free the memory area in the following manner:
+.Bl -enum
+.It
+First, the
+.Ar ld_s
+field of each
+.Vt Dwarf_Locdesc
+descriptor should be deallocated using the allocation type
+.Dv DW_DLA_LOC_BLOCK .
+.It
+Then, the application should free each
+.Vt Dwarf_Locdesc
+descriptor using the allocation type
+.Dv DW_DLA_LOCDESC .
+.It
+Finally, the
+.Va llbuf
+pointer should be deallocated using the allocation type
+.Dv DW_DLA_LIST .
+.El
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Ar at ,
+.Ar llbuf
+or
+.Ar listlen
+was NULL.
+.It Bq Er DW_DLE_ARGUMENT
+The attribute provided by argument
+.Ar at
+does not contain a location expression or is not associated with a
+location expression list.
+.El
+.Sh EXAMPLE
+To retrieve the location list associated with an attribute, use:
+.Bd -literal -offset indent

+.Sh DESCRIPTION
+Function
+.Fn dwarf_loclist_from_expr
+translates DWARF location expression bytes into a
+.Vt Dwarf_Locdesc
+descriptor.
+The size for address related data is taken to be the default address
+size for the object being read.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF debug context allocated using
+.Xr dwarf_init 3 .
+.Pp
+Argument
+.Ar bytes_in
+should point to an array of DWARF location expression bytes.
+.Pp
+Argument
+.Ar bytes_len
+should specify the number of the location expression bytes to be
+translated.
+.Pp
+Argument
+.Ar llbuf
+should point to a location which will be set to a pointer
+to a returned
+.Vt Dwarf_Locdesc
+descriptor.
+.Pp
+Argument
+.Ar listlen
+should point to a location which will hold the number of the
+.Vt Dwarf_Locdesc
+descriptors returned.
+In this case it is always set to 1.
+.Pp
+If argument
+.Ar err
+is not NULL, it will be used to store error information in case of an
+error.
+.Pp
+Function
+.Fn dwarf_loclist_from_expr_a
+is identical to function
+.Fn dwarf_loclist_from_expr ,
+except that it requires one additional argument
+.Ar addr_size ,
+which specifies the address size to use when translating the location
+expression bytes.
+.Pp
+Function
+.Fn dwarf_loclist_from_expr_b
+is identical to function
+.Fn dwarf_loclist_from_expr_a
+except that it requires two additional arguments for translating the
+location expression bytes.
+Argument
+.Ar offset_size
+specifies the offset size, and argument
+.Ar version
+specifies the DWARF version.
+These values are required to correctly translate the
+.Dv DW_OP_GNU_implicit_pointer
+opcode.
+.Ss Memory Management
+The memory area used for the descriptor returned in argument
+.Ar llbuf
+is allocated by
+.Lb libdwarf .
+When the descriptor is no longer needed, application code should use
+function
+.Xr dwarf_dealloc 3
+to free the memory area in two steps:
+.Bl -enum -compact
+.It
+First, the array of
+.Vt Dwarf_Loc
+descriptors pointed to by the
+.Ar ld_s
+field of the
+.Vt Dwarf_Locdesc
+descriptor should be deallocated using the allocation type
+.Dv DW_DLA_LOC_BLOCK .
+.It
+Next, the application should free the
+.Ar llbuf
+pointer using the allocation type
+.Dv DW_DLA_LOCDESC .
+.El
+.Sh RETURN VALUES
+On success, these functions returns
+.Dv DW_DLV_OK .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions may fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_LOC_EXPR_BAD"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Va dbg ,
+.Va bytes_in ,
+.Va llbuf
+or
+.Va listlen
+was NULL.
+.It Bq Er DW_DLE_ARGUMENT
+Argument
+.Ar bytes_len
+was 0.
+.It Bq Er DW_DLE_ARGUMENT
+The value of argument
+.Ar addr_size
+was invalid.
+.It Bq Er DW_DLE_LOC_EXPR_BAD
+An unknown or invalid operation was found in the location expression
+bytes provided in argument
+.Ar bytes_in .
+.It Bq Er DW_DLE_MEMORY
+An out of memory condition was encountered during the execution of
+this function.

+.Sh DESCRIPTION
+These functions are used to step through compilation or type units
+associated with a DWARF debug context, optionally returning information
+about the unit.
+.Pp
+Function
+.Fn dwarf_next_cu_header_c
+is the API recommended for new application code.
+Function
+.Fn dwarf_next_cu_header
+and
+.Fn dwarf_next_cu_header_b
+can only operate on compilation units associated with the
+.Dq \&.debug_info
+section.
+They are less general than function
+.Fn dwarf_next_cu_header_c ,
+and are deprecated for use by new application code.
+.Pp
+Argument
+.Ar dbg
+should reference a DWARF debug context allocated using
+.Xr dwarf_init 3 .
+If argument
+.Ar is_info
+is set to 1,
+the function returns information for compilation units found in the
+.Dq \&.debug_info
+section.
+If argument
+.Ar is_info
+is set to 0,
+the function returns information for type units found in the
+.Dq \&.debug_types
+sections.
+Argument
+.Ar cu_length
+should point to a location that will be set to the
+length of the compilation or type unit.
+Argument
+.Ar cu_version
+should point to a location that will be set to the
+version number for the compilation or type unit.
+Argument
+.Ar cu_abbrev_offset
+should point to a location that will be set to the
+starting offset (in the
+.Dq .debug_abbrev
+section) of the set of debugging information entry abbreviations
+associated with this compilation or type unit.
+Argument
+.Ar cu_pointer_size
+should point to a location that will be set to the
+size in bytes of an address for the machine architecture of the
+underlying object being debugged.
+Argument
+.Ar cu_offset_size
+should point to a location that will be set to the
+size in bytes for a DWARF offset in the compilation or type unit.
+Argument
+.Ar cu_extension_size
+is only needed for processing MIPS/IRIX objects that use
+a non-standard DWARF format.
+It should point to a location that will be set to 4 for normal
+objects and to 0 for non-standard ones.
+Argument
+.Ar type_signature
+and
+.Ar type_offset
+is only needed for processing type units.
+Argument
+.Ar type_signature
+should point to a location that will be set to the 64-bit unique signature
+of the type described in the type unit.
+Argument
+.Ar type_offset
+should point to a location that will be set to the offset of the debugging
+information entry that describes the type.
+Argument
+.Ar cu_next_offset
+should point to a location that will be set to the
+offset of the next compilation unit header in the
+.Dq \&.debug_info
+section,
+or the offset of the next type unit header in the
+.Dq \&.debug_types
+section.
+Argument
+.Ar err
+should point to a location that will hold an error descriptor in case
+of an error.
+.Pp
+Function
+.Fn dwarf_next_cu_header_b
+is identical to function
+.Fn dwarf_next_cu_header_c
+except that it does not provide arguments
+.Ar is_info ,
+.Ar type_signature
+and
+.Ar type_offset .
+.Pp
+Function
+.Fn dwarf_next_cu_header
+is identical to function
+.Fn dwarf_next_cu_header_b
+except that it does not provide arguments
+.Ar cu_offset_size
+and
+.Ar cu_extension_size .
+.Pp
+A value of NULL may be used for any of the arguments
+.Ar cu_length ,
+.Ar cu_version ,
+.Ar cu_abbrev_offset ,
+.Ar cu_pointer_size ,
+.Ar cu_offset_size ,
+.Ar cu_extension_size ,
+.Ar type_signature ,
+.Ar type_offset ,
+.Ar cu_next_offset
+and
+.Ar err
+if the caller is not interested in the respective value.
+.Ss Iterating Through Compilation Units in a Debug Context
+.Pp
+The first call to function
+.Fn dwarf_next_cu_header_c
+for a given debug context with argument
+.Ar is_info
+set to 1 will return information about the first
+compilation unit in the
+.Dq \&.debug_info
+section.
+Subsequent calls to the function will iterate through the remaining
+compilation units in the section.
+On stepping past the last compilation unit in the section,
+function
+.Fn dwarf_next_cu_header_c
+returns
+.Dv DW_DLV_NO_ENTRY
+and resets its internal state.
+The next call to the function will restart from the first compilation
+unit in the section.
+.Ss Iterating Through Type Units in a Debug Context
+When a DWARF debug context is allocated using
+.Xr dwarf_init 3 ,
+an internal pointer associated with the context will point to the first
+.Dq \&.debug_types
+section found in the debug object.
+The first call to function
+.Fn dwarf_next_cu_header_c
+for the debug context with argument
+.Ar is_info
+set to 0 will return information about the first
+type unit in that
+.Dq \&.debug_types
+section.
+Subsequent calls to the function will iterate through the remaining
+type units in the section.
+On stepping past the last type unit in the debug context,
+function
+.Fn dwarf_next_cu_header_c
+returns
+.Dv DW_DLV_NO_ENTRY
+and resets its internal state.
+The next call to the function will restart from the first type
+unit in the
+.Dq \&.debug_types
+section.
+.Pp
+If the debug object contains multiple
+.Dq \&.debug_types
+sections, the function
+.Fn dwarf_next_types_section
+can be called to move the internal pointer to the next
+.Dq \&.debug_types
+section.
+As a result, subsequent calls of the function
+.Fn dwarf_next_cu_header_c
+will operate on the new
+.Dq \&.debug_types
+section.
+Function
+.Fn dwarf_next_types_section
+returns
+.Dv DW_DLV_NO_ENTRY
+when there are no more
+.Dq \&.debug_types
+sections left in the debug object.
+.Sh RETURN VALUES
+On success, these functions return
+.Dv DW_DLV_OK .
+In case of an error, they return
+.Dv DW_DLV_ERROR
+and set argument
+.Ar err .
+When there are no more compilation units left to traverse, they return
+.Dv DW_DLV_NO_ENTRY .
+.Sh ERRORS

+.Sh DESCRIPTION
+.Pp
+The
+.Fn dwarf_object_init
+function allocates and returns a
+.Vt Dwarf_Debug
+instance that uses application-supplied access methods to read file
+content.
+.Pp
+The argument
+.Ar iface
+should point to a populated
+.Vt Dwarf_Obj_Access_Interface
+structure.
+The contents of the
+.Vt Dwarf_Obj_Access_Interface
+structure are described in the section
+.Sx "Object Access Functions"
+below.
+.Pp
+The argument
+.Ar errhand
+should point to a function to be called in case of an error.
+If this argument is
+.Dv NULL
+then a default error handling scheme is used.
+See
+.Xr dwarf 3
+for a description of the error handling schemes available.
+.Pp
+The argument
+.Ar errarg
+will be passed to the error handler function pointed to by argument
+.Ar errhand .
+.Pp
+The argument
+.Ar dbg
+should point to a memory location that will be set to a reference to
+the returned
+.Vt Dwarf_Debug
+descriptor.
+.Pp
+The argument
+.Ar err
+will be used to return a
+.Vt Dwarf_Error
+descriptor in case of an error.
+.Ss Object Access Functions
+The data structures used to specify object access methods are defined
+in
+.In libdwarf.h .
+.Bl -tag -width indent
+.It Vt "Dwarf_Obj_Access_Interface"
+This structure bundles together a set of file access methods along
+with a pointer to application-private state.
+.Bd -literal -offset indent
+typedef struct {
+	void *object;
+	const Dwarf_Obj_Access_Methods *methods;
+} Dwarf_Obj_Access_Interface;
+.Ed
+.Pp
+.Bl -tag -width ".Ar methods" -compact
+.It Ar object
+This field points to application-specific state that will be passed as
+the first parameter to the actual access object methods.
+.It Ar methods
+This structure contains pointers to the functions implementing the
+access methods, as described below.
+.El
+.It Vt Dwarf_Obj_Access_Methods
+This structure specifies the functions implementing low-level access.
+.Bd -literal -offset indent
+typedef struct {
+	int (*get_section_info)(void *obj, Dwarf_Half index,
+	    Dwarf_Obj_Access_Section *ret, int *error);

+} Dwarf_Obj_Access_Methods;
+.Ed
+.Pp
+.Bl -tag -width ".Ar get_section_count" -compact
+.It Ar get_byte_order
+This function should return the endianness of the DWARF object by
+returning one of the constants
+.Dv DW_OBJECT_MSB
+or
+.Dv DW_OBJECT_LSB .
+.It Ar get_length_size
+This function should return the number of bytes needed to represent a
+DWARF offset in the object being debugged.
+.It Ar get_pointer_size
+This function should return the size in bytes, in the object being
+debugged, of a memory address.
+.It Ar get_section_count
+This function should return the number of sections in the object being
+debugged.
+.It Ar get_section_info
+This function should return information about the section at the
+index
+.Ar ndx
+by filling in the structure of type
+.Vt Dwarf_Obj_Access_Section
+pointed to by argument
+.Ar ret .
+The
+.Vt Dwarf_Obj_Access_Section
+structure is described below.
+.It Ar load_section
+This function should load the section specified by argument
+.Ar ndx
+into memory and place a pointer to the section's data into
+the location pointed to by argument
+.Ar ret_data .
+.El
+.Pp
+The argument
+.Ar obj
+passed to these functions will be set to the pointer value in the
+.Ar object
+field of the associated
+.Vt Dwarf_Obj_Access_Interface
+structure.
+.Pp
+The argument
+.Ar error
+is used to return an error code in case of an error.
+.It Vt Dwarf_Obj_Access_Section
+This structure describes the layout of a section in the DWARF object.
+.Bd -literal -offset indent
+typedef struct {
+	Dwarf_Addr addr;
+	Dwarf_Unsigned size;
+	const char *name;
+} Dwarf_Obj_Access_Section;
+.Ed
+.Pp
+.Bl -tag -width ".Ar name" -compact
+.It Ar addr
+A pointer to the start of the section's data.
+.It Ar size
+The size of the section in bytes.
+.It Ar name
+A pointer to a NUL-terminated string containing the name of the
+section.
+.El
+.El
+.Sh RETURN VALUES
+On success, the
+.Fn dwarf_object_init
+function returns
+.Dv DW_DLV_OK .
+In case of an error, the function returns
+.Dv DW_DLV_ERROR
+and sets the argument
+.Ar err.
+.Sh ERRORS
+The
+.Fn dwarf_object_init
+function may fail with the following errors:
+.Bl -tag -width ".Bq Er DW_DLE_DEBUG_INFO_NULL"
+.It Bq Er DW_DLE_ARGUMENT
+One of the arguments
+.Ar iface
+or
+.Ar dbg
+was NULL.
+.It Bq Er DW_DLE_DEBUG_INFO_NULL
+The underlying object did not contain debugging information.
+.It Bq Er DW_DLE_MEMORY
+An out of memory condition was encountered during the execution of the
+function.

+.Fc
+.Sh DESCRIPTION
+These functions allocate and return a
+.Vt Dwarf_P_Debug
+descriptor representing a DWARF producer instance.
+.Pp
+The argument
+.Ar errhand
+should contain the address of a function to be called in case of an
+error.
+If this argument is
+.Dv NULL ,
+the default error handling scheme is used, see
+.Xr dwarf 3 .
+.Pp
+The argument
+.Ar errarg
+will be passed to the error handler function when it is invoked.
+.Pp
+The argument
+.Ar err
+references a memory location that would hold a
+.Vt Dwarf_Error
+descriptor in case of an error.
+.Pp
+The argument
+.Ar flags
+specifies additional characteristics of the DWARF producer instance.
+The following flags are recognized:
+.Pp
+.Bl -tag -width "Dv DW_DLC_ISA_MIPS"
+.It Dv DW_DLC_ISA_IA64
+.Pq Deprecated
+The target instruction set architecture is IA64.
+This flag is deprecated.
+Application code should use the
+.Xr dwarf_producer_set_isa 3
+function to specify target instruction set architecture.
+.It Dv DW_DLC_ISA_MIPS
+.Pq Deprecated
+The target instruction set architecture is MIPS.
+This flag is deprecated.
+Application code should use the
+.Xr dwarf_producer_set_isa 3
+function to specify target instruction set architecture.
+.It Dv DW_DLC_SIZE_32
+.Pq Default
+The target address size is 32-bit.
+.It Dv DW_DLC_SIZE_64
+The target address size is 64-bit.
+.It Dv DW_DLC_STREAM_RELOCATIONS
+.Pq Default
+Generate stream relocations.
+.It Dv DW_DLC_SYMBOLIC_RELOCATIONS
+Generate symbolic relocations.
+.It Dv DW_DLC_TARGET_BIGENDIAN
+The target is big endian.
+.It Dv DW_DLC_TARGET_LITTLEENDIAN
+The target is little endian.
+.It Dv DW_DLC_WRITE
+.Pq Required
+Permit writing of DWARF information.
+.El
+.Pp
+The following flags are mutually exclusive.
+.Bl -bullet -compact
+.It
+Flags
+.Dv DW_DLC_ISA_IA64
+and
+.Dv DW_DLC_ISA_MIPS .
+.It
+Flags
+.Dv DW_DLC_SIZE_32
+and
+.Dv DW_DLC_SIZE_64 .
+.It
+Flags
+.Dv DW_DLC_STREAM_RELOCATIONS
+and
+.Dv DW_DLC_SYMBOLIC_RELOCATIONS .
+.It
+Flags
+.Dv DW_DLC_TARGET_BIGENDIAN
+and
+.Dv DW_DLC_TARGET_LITTLEENDIAN .
+.El
+If neither of the flags
+.Dv DW_DLC_TARGET_BIGENDIAN
+and
+.Dv DW_DLC_TARGET_LITTLEENDIAN
+is set, the target's endianness is assumed to be the same as the host's
+endianness.
+.Pp
+Argument
+.Ar func
+should point to an application-provided callback function of type
+.Vt Dwarf_Callback_Func_b .
+The type
+.Vt Dwarf_Callback_Func_b
+is defined in the header file
+.In libdwarf.h
+as:
+.Bd -literal -offset indent
+typedef int (*Dwarf_Callback_Func_b)(char *name, int size,
+    Dwarf_Unsigned type, Dwarf_Unsigned flags, Dwarf_Unsigned link,
+    Dwarf_Unsigned info, Dwarf_Unsigned *index, int *error);
+.Ed
+.Pp
+This function is called by the
+.Lb libdwarf
+once for each section in the object file that the library needs to
+create.
+The arguments to this callback function specify the values in the ELF
+section header for the section being created:
+.Pp
+.Bl -tag -width indent -compact -offset indent
+.It Ar name
+The name of the section being created.
+.It Ar size
+The
+.Va sh_size
+value in the section header.
+.It Ar type
+The
+.Va sh_type
+value in the section header.
+.It Ar flags
+The
+.Va sh_flags
+value in the section header.
+.It Ar link
+The
+.Va sh_link
+value in the section header.
+.It Ar info
+The
+.Va sh_info
+value in the section header.
+.El
+.Pp
+On success, the callback function should return the section index
+value of the created section, and set the location pointed to by
+argument
+.Ar index
+to the symbol table index of the symbol that associated with the newly
+created section.
+This symbol table index will be used in relocation entries
+referring to the created section.
+.Pp
+In case of failure, the callback function should return -1 and set the
+location pointed to by argument
+.Ar error
+to an application-defined error code.
+This application returned error code is currently ignored by the
+library.
+.Pp
+Function
+.Fn dwarf_producer_init
+is deprecated.
+Function
+.Fn dwarf_producer_init
+is identical to function
+.Fn dwarf_producer_init_b
+except that the callback function it expects can not properly handle
+arbitrary section symbol index values.
+.Ss Memory Management
+The
+.Vt Dwarf_P_Debug
+instance returned by these functions should be freed using the
+function
+.Fn dwarf_producer_finish .
+.Sh RETURN VALUES
+On success, these functions return the created DWARF producer
+descriptor.
+In case of an error, they return
+.Dv DW_DLV_BADADDR
+and set the argument
+.Ar err .
+.Sh ERRORS
+These functions can fail with:
+.Bl -tag -width ".Bq Er DW_DLE_NO_ENTRY"
+.It Bq Er DW_DLE_ARGUMENT
+Argument
+.Ar func
+was NULL.
+.It Bq Er DW_DLE_ARGUMENT
+The flag
+.Dv DW_DLC_WRITE
+was not set in argument
+.Ar flags .
+.It Bq Er DW_DLE_ARGUMENT
+The flags
+.Dv DW_DLC_SIZE_32

+An out of memory condition was encountered.
+.El
+.Sh EXAMPLES
+To initialize a
+.Vt Dwarf_P_Debug
+instance for a MIPS32 big endian object, use:
+.Bd -literal -offset indent
+Dwarf_P_Debug dbg;
